We also offer higher yield variants of carbon steel flanges like F52, F60, F65, and F70 (all per A694).
These are heat treated carbon steel with a higher yield strength than common A105 flanges with a 35K yield strength minimum.
If your application calls for low temperature service, consider A350 LF2 carbon flanges (with Charpy V-Notch Impact Tests at -50°F) or the superior LF3 (CVNs at -150°F)
WHY USE HIGH YIELD CARBON STEEL FLANGES?
The yield strength is a characteristic of steel in which the material in question can withstand deformation. The point of stress in relation to said material in which plasticity deformation occurs is known as the yield point. This point is the maximum allowable load bearing occurrence upon which the steel material should be subjected. Yielding is a gradual failure measure which occurs over a period of time and in which case deformation is observable.
